On suggestion of a tantrik, a man yearning for a son abducted and killed a two-year-old boy for human sacrificial ritual. The man, a school bus driver, and his two wives were arrested today for the horrendous crime, said Indore Police. After his wife died 12 years ago, he got married twice over a period of time as he wanted a son. He then approached a tantrik (sorcerer) who advised him to perform a human sacrifice ritual to get his wish fulfilled, the DIG said.
